Who Needs Transistors?

Should I go buy a nano soldering iron ? I think this may be OK on paper but I doubt we will see this in real world applications any time soon.

Perhaps yes. You may need no soldering iron for bonding the transistors and you be educating some bacteria to do it for you or they may be connected or disconnected using laser (nano soldering iron).

Using genetic material for information storage is not new. It has been in use for about 25 years. It gives 3D storage space due to its structure. Then there was bacteria chip by www.ornl.gov built for sensing mine / explosives burried in the ground.

Perhaps users will get the parts made for application with lots of things on a chip and not just a transistor. These you can perhaps know as functional blocks. Why to design if you get one for a purpose or join the nano design team if that is what you want to do.

There is great chance of technology going down the drain like Transputer Technology or Magnetic Bubble Memory Technology. These two great technology never were in real use.

These poeple are talking about bits 1/0 when they call it a molecular switch. They are not talking about that S-slope of the transistor that give analog gain. So hold on. They are no where near in complete transistor idea or are they.

HP also has serious problem of nano soldering and they are away from achieving it. They may do it soon. I think lots of technology are merging together into new world. Quantum dots, supper conducting nano wires, and now nano molecular switches. We can think of Terra Hz computers. Unfortunately, these are a bit away from soldering iron technology.

If only tool one has is a hammer, then every problem looks like a nail.

"...using laser (nano soldering iron)."

We're talking molecular-scale thingies here, yes? 'Fraid a laser won't do. Too big. Way too big. Electron beams, maybe. But not lasers.

Personally, I liked your idea of bacteria doing the work (so I'd better get busy and start training mine. Tools are still an issue tho...)

Laser is the only way we can deal with molecular level information. Perhaps x-ray lasers that were developed by IBM long ago will be made public. There has been lots of developments but most of it kept away from public use.
